Problems solved by technology

[0006] Some medium and trace element fertilizers disclosed in the prior art contain medium and trace elements, but do not adjust the soil pH value, and in the process of using a granulator to granulate the fertilizer, the base material is easy to accumulate and cannot be evenly dispersed, resulting in The granulation is uneven, and the inclination angle of the granulation disc cannot be adjusted arbitrarily, so it cannot meet the granulation requirements of different specifications.

Abstract

The invention discloses a medium trace element fertilizer for adjusting alkaline soil and a preparation method thereof. The medium trace element fertilizer comprises the following components in percentage by mass: 40-60% of medium trace element-containing substances, 30-50% of acidic substances and 1-10% of auxiliaries. The medium trace element is a mixture containing two or more of calcium, magnesium, silicon, sulfur, iron, manganese, copper, zinc, boron and molybdenum; the acidic substance is one or a mixture of more than two of urea sulfate, citric acid, methylene succinic acid, maleic acid, oxalic acid, acetic acid and hexadienoic acid; the auxiliary is one or a mixture of more than two of xanthan gum, guar gum, biochemical fulvic acid, molasses, chitosan oligosaccharide, ethylene glycol, polyethylene glycol and ethanolamine. On one hand, trace elements in soil are supplemented, on the other hand, the PH value of the soil is improved, and absorption of crops to the trace elements is promoted.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a medium and trace element fertilizer for regulating alkaline soil and a preparation method thereof. Background technique [0002] According to the data estimated by the National Agricultural Technology Extension Center in 2014, my country's soil generally lacks medium and trace elements. The areas of cultivated land where the content of trace elements such as calcium, magnesium, sulfur, iron, manganese, copper, zinc, boron, and molybdenum in soil in my country are below the critical value reach 63%, 53%, 40%, 31%, 48%, and 25%, respectively. %, 42%, 84%, 59%. Compared with the data of the second national soil census more than 30 years ago, the area of ​​cultivated land lacking medium and trace elements has nearly doubled. [0003] Because crops have a large demand for macronutrients and have the most obvious impact on yield, in the past fertilization habits only focused on ...
